INDUSTRIAL INTEREST

A number of polysaccharides of vegetal origin, like cellulose and starch, are extensively studied polymers with established industrial applications. Fragments obtained by chemical or enzymatic depolymerization of these and other polysaccharides also find wide applications in the pharmaceutical and food industries. Among these oligosaccharides, the starch-derived cyclodextrins are endowed with the unique property of forming inclusion complexes with a number of organic molecules whose size and shape fit into their macrocycles; such an inclusion can be exploited for protecting the guest molecules, modify their intrinsic solubility, and properly vectorize them. Other industrial polysaccharides such as chitin and chitosan and their fragments are finding wide applications in the food and pharmaceutical industry. Elucidation of the structure of polysaccharides from yeast, fungi and lichens (mainly mannans, galactans and glucans) provides new taxonomic criteria for these natural polymers. Advances in morphological and structural analysis of oligo- and polysaccharides and their derivatives permit a deeper insight into structural features important in determining their optimal application in various fields and to generate new products.
